from my server config file, I have
set g_logsync "2" //0=no log, 1=buffered, 2=continuous, 3=append
from
Urban Terror Manual :
# set g_logsync "1": Enables/disables direct writing to the log file instead of buffered. (Default 1)
I have set "2" on my servers and it works fine.
Also I'd like to know, if B3 would work properly without setting g_loghits to 1.
B3 will work
some b3 plugins will not work (or will send a rcon command to your server to force g_loghits to 1)
